同时亦对影响土壤冻结深度的温度因子做了探讨。
The law of annual variations of frozen depth and the charateristics of water moving to freezing interface were analyzed.
采用有限差分方法，完成了土基冻结逐渐进行且伴随有湿迁移的路面体温度场的计算和冻结深度的确定。
Using the finite differential method we calculate the temperature field and frozen depth of pavement proper when the road is freezing by degrees with moisture migration.
贴坡排水层的顶部应高于坝体浸润线的逸出点，超出的高度务使坝体浸润线位于该地区冻结深度以下，且不小于1.5米。
Its top must be higher than dam saturation line's exit point, and the extent exceeded must ensure the saturation line is no less than 1.5 meters below local freezing depth.
